Painful Abdominal Outpouching in an Adult Male

Post-herpetic abdominal pseudohernia is a neurologic complication of herpes zoster resulting from paresis of the abdominal wall muscles ipsilateral to the eruption. This poorly known condition may raise suspicion for true abdominal wall hernia or other concerning etiologies, resulting in extensive work-up and imaging. Post-herpetic abdominal pseudohernia is a relatively benign condition, which resolves spontaneously in the majority of cases. Therefore, it is important for the clinician to be aware of this complication in order to avoid unnecessary imaging or excessive management, which may increase the cost of care and burden to the patient.
